"We hadn't been on Thustra ten standard hours before the natives, the Sephi, attacked our outpost. Our orders were specific. Establish a 'beachhead,' make a strong show of force, but avoid engaging the Sephi at all costs. No one told them that."

The Sephi's discontent with Republic rule soon turned into hostility and open acts of defiance. Through a combination of guerrilla warfare and terrorist tactics, the subversives tried to weaken the Republic occupation force through attrition. Despite the fact that such aggression clearly constituted as acts of treason and war, the government on Coruscant hoped to find a resolution to the dilemma that resulted with Thustra's continued allegiance to the Galactic Republic. Yoda, the Grand Master of the Jedi Order and the leading member of its ruling body, personally undertook the assignment as an emissary of the Republic.

Upon Yoda's arrival on Thustra, however, the Grand Army and its Jedi officers were in a desperate situation. Two Jedi Generals, Tyffix and Tyr, were murdered by a terrorist surprise attack. Their deaths left the young CommandersCal and Pix in charge of the occupation. Yoda, with Cal at his side, departed for the capitalcity of Thustra in a final attempt to negotiate a cessation of hostilities between the Republic and the Sephi; PadawanPix and CommanderClutch were ordered to remain behind in command of the occupation force.

Due to the fact that the Sephi rebellion was supported by Thustra's own ruler, KingAlaric, Windu believed that appeasement was unwise; Thustra had to be subdued by the application of force, rather than just the mere threat of it. Palpatine was absolutely adamant that Thrusta could not be allowed to withdraw from the Republic as the cost would be too great. Given Alaric's influence within his own region, the Chancellor pointed out that the entire Sumitra sector was capable of seceding from the Republic if Thustra was allowed to do so. As an old friend of the King, Yoda hoped to convince Alaric to renew Thustra's loyalty to the Republic.[3]

"Even more delicate this situation has become with the arrival of these additional forces. Move against the Sephi, and derailed my negotiations will be. Pix, your position here, are you to hold.""What if you don't return?"

Commander Pix and Commander Clutch launch a preemptive strike on the Sephi rebels of Thustra.

Shortly after arriving on Thustra, Yoda traveled to the Sephi capitalcity with only Cal accompanying him. Pix, who remained behind to command the Republic's armed forces, was under strict instructions to not move against the Sephi, so as to not undermine Yoda's negotiation attempt. Although Alaric was willing to speak with the Grand Master of the Jedi Order, neither of the two old friends were able to sway the other from their views. Alaric, who argued that the Republic was broken and corrupt, insinuated that the Republic could eventually betray the Jedi who defended it. However, Yoda remained resolute in his allegiance to the Republic, thus leaving the two at an impasse.[3]

After the King placed the Jedi under house arrest, SenatorNavi of Thustra, a loyalist but corrupt politician, moved to manipulate the Republic into restoring order on Thustra through military force. First, he provided Cal with information that would enable the Jedi to escape from the palace. Navi then informed Pix that Yoda and Cal had been executed on King Alaric's orders. The young Jedi Commander was convinced by the Sephi Senator's deception and, as Navi predicted, retaliated with an all-out attack on the Sephi capital. In order to ensure a Republic victory, Navi provided Pix with the most recent Sephi troop movements, as well as information on Alaric's palace.[3]

At the same time, Moje, an aide to Senator Navi, discreetly circulated rumors of a Jedi plot to assassinate Alaric, and thus incited even greater anti-Republic sentiment amongst the Navi. Commander Pix, along with CommanderClutch at her side, personally led the clone troopers into battle against the Sephi forces that stood between the Republic's army and the capital of Thustra. While Pix and Clutch commanded the ground forces during the firefight, the Republic launched an aerial bombardment on the Sephi, resulting in many enemy casualties, including Commander Dekluun.[3]

Meanwhile, Cal and Yoda were attacked by the King's palace guards, resulting in Cal's death. Yoda moved to confront his former friend alone, only to discover that Alaric decided to die as a martyr in order to further incite the Sephi to rebel against the Republic. Although his goal was achieved, Alaric, in his dying moments, begged Yoda to remember their friendship as it was in the past, rather than what it had become due to the Clone Wars.[3]

On Coruscant, Senator Navi attempted to use the situation on Thustra to his advantage in order to gain support from his fellow delegates in the Galactic Senate. However, he was caught by surprise when Yoda, Pix and Clutch entered the rotunda of the Senate Building where they revealed the Sephi politician's duplicity to the other senators. Navi was arrested and charged with treason, but the Republic's withdrawal from Thustra enabled the Sephi to secede from the Galactic Republic.[3]
